OH1 Indoor Conditions



Intent 1:

To limit the probability of:

  • inadequate ventilation, which could lead to high relative humidity and the accumulation of moisture,
  • insect infestation, or
  • the ingress of precipitation.

This is to limit the probability of:

  • the generation of pollutants from biological growth or from materials that become unstable on wetting, or
  • deterioration, which could lead to compromised integrity of environmental separators or of elements protected by the separators.

This is to limit the probability of negative effects on the air quality of indoor spaces, which could lead to harm to persons.
